. a 1/! whom it mayconoem:

Be it known that I, LEsLIn ARTHUR \VAGNER, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles. State ofCalifornia, have invented new and useful. Improvements in DryingMachines, of which the following is a specification.

The present invention relates to laundry machinery, and it. is an objectof the in vention to provide a simple, effective and easily operatedmachine which will exp editiously dry clothes; and a machine in suchform that .it may be used effectively for washing clothes as well.

Clothes being washed by the machinery now in common use, are washed in awasher then wrung in an extractor and then finally dried in a dryer.This not only necessitates a great deal of handling from one machine tothe other but also requires considerable time and is hard on theclothes. By my present improvements in the drying of clothes I amenabled not only most efliciently to dry them, but also to wash them inthe same machine, it being unnecessary to handle them until they havebeen washed and dried. The machine first operates as a washer, and whenthe clothes are thoroughly washed the operator opens and closes propervalves thereby causin the machine to operate as a dryer; the c othesremainin in the machine until they are thoroughy dried. If however, theclothes are to be mangled they may be removed from the machine whenslightly damp,

My invention greatly simplifies the washing and drying of clothes andsaves time and labor. The manner in which these results are accomplishedand the construction are prefera modified form of the invention; andFig. 5 is a detail of a modified form of the in vention.

In the drawings numeral 10 designates a stationary drum or holder, 11the inner drum or rotor and 12 the legs or supports for holder 10. Theholder 10 may be made in any suitable manner, for instance, it may bemade of a cylindrical wall 13 and ends 14 and 14 which are fastened toangles 15 said angle brackets cast integral with legs 12. Within theholder 10 is rotor 11. The rotor 11 may comprise a cylindrical wall 19and ends 20 and 21. The rotor is suspended within the holder by means ofshafts 22 and 23 which run in bearings 16 and 17. Bearings 16 and 17 aresecured to ends 14 and 14", respectively, by means of bolts 18. Theshaft 22 is secured in rotor end 20 as shown in Fig. 1, while shaft 23may be cast integral with end 21. Within the rotor 11 are paddles 24which extend the entire length of the rotor and project radiallyinwardly from the outer cylindrical wall. These paddles 24 are shaped asshown in 'Fig. 2, being flange-riveted to the cylinder 19 and their endsfitting over bosses 26 and 27 on ends 20 and 21, res ectively. Extendingthrough shaft 23 is ole 28 which leads from swivel coupling 29 topassage ways 30. The passage ways, which 1y cored holes in the end 21,extend radially outwardly to and -t hr0ugh bosses 27 and 0 en into the.interiors of paddles 24. In'the inward surface of paddles 24 aredischarge holes 31. The cylindrical wall 19 of rotor 11 has perforations32 as shown in Figs. 1 and 2.

The operation of the machine is as follows: The clothes are put into therotor 11 through door 38 in the rotor, and door 39 in the holder. Themachine is first used as a washer; vacuum valve A and drain valve E areclosed and water valve D is opened. Water or washing liquid enters theholder from pipe 33 through pipe 34. When the proper amount of water hasentered holder 10, water valve D is closed. Air valve F is closed whilethe machine is being operated as a washer. The rotor 11 is then rotatedor oscillated in the manner common to washing machines by means ofpinion 35 and ar 36 which is mounted upon shaft 23. he clothes arethoroughly and quickly washed in the water or other fluid by theagitation caused by paddles 24. When the clothes have been thoroughlywashed, drain valve E is opened allowing the water or washing com oundto drain from the holder through pipes 34 and 40. When the holder 10 iscom letely drained, drain valve E is closed an vacuum valve A may beopened, causing a partial vac uum in holder 10. Any suitable vacuum pumpor other apparatus may'be used. Hot air valve F is then opened allowingdry warm air to enter the rotor 11 from ipe 42,.through swivel joint 29,hole 28 in s aft 23, thence through passage wa s 30 into paddles 24where it blows into 1; e rotor 11 through perforations 31. This air maybe drawn inby the vacuum or it may be forced in by pressure, or both. Ifit is desired to use air at ordinary temperatures rather than warm air,valve can be 0 ened instead of hot air valve F, thereby a lowing airfrom pipe 27 to enter the rotor. The machine 'operating in this mannervery quickly dries the clothes.

In Figs. 4 and 5 I show a modified form of the invention. In theforegoing described form the construction is adapted to be of metal; andin the form now to be described I adapt my invention to a woodenconstruction. This form also shows how the invention may be applied toany existing washer. In this form 'the paddles 24 are solid and shaft23"is pivoted with a bored passage way 28". into which pipes 30 areconnected. ipes 30" extend outward from shaft 23to a point 30 near therim of end 21" where they pass through said end and extend alon thecylinder 19 next to paddles 24. T ere may be one pipe h each paddle orthere maybe a pipe on each side of each paddle as shown In Fig. 4. Thereare holes 31 in pi es 30 through which the air passes into t e rotor 11.It will be understood that the operation may be varied to suitcircumstances and that the above description is intended only to betypical. Rinsing water may be put through the machine from the paddlesbefore drying the clothes; and many other variations of use will readilyoccur to those skilled in the art. And, furthermore, I do 'not intendthe foregoing specific description to be a limitation of my invention,believing it to be broad in its nature and not specifically limitedexcept as so stated in the following claim.

Having described a preferred form of my invention, I claim:

A drying machine, com rising a cylindrical -rotary hollow clot escarrier, inwardly projecting peri herally spaced and axially extendingpad les in the inner cylindrical surface of the carrier to disturb theclothes during rotation of the carrier, the paddles being hollow,extending substantially the whole length of the carrier and beingperforated substantially throughout their length, and means to feeddrylng air into the hollow paddles regardless of theirposition ofrotation,

In witness that I claim the fore 'ing I have hereunto subscribed my namet' is 12th day of- March, 1919.
